A friend gave me one of Adafruit’s circuit playgrounds (developer edition) to use, and I wanted to see would it make a good robot controller. The circuit playground is packed full of features like sensors, neo-pixels and even an accelerometer.
I wanted to add a L9110 motor controller and create a small bot I could use to show some of the expansion possibilities. The circuit playground uses the standard Arduino IDE so its has a huge amount of libraries and examples on the web to use.
I also wanted to make something robust that wouldn’t have a lot of wires exposed, so beginners or children could use my bot and learn to program.
Adding bluetooth was also a goal which I talk about later in this article.
